PART 1 - INTRODUCTION
General
Application Versatility
The D901/M ultrasonic flow meter is designed to measure the fluid velocity of liquid within closed conduit. The transducers are a non-contacting, clamp-on type, which will provide benefits of non-fouling operation and ease of installation.
The flow meter operates by transmitting an ultrasonic sound from its transmitting transducer through the pipe wall into the flowing liquid. The sound will be reflected by suspended particles or bubbles within the liquid and recorded by the receiving transducer. A frequency shift (Doppler effect) will occur that is directly related to the speed of the moving particle or bubble. This shift in frequency is interpreted by the instrument and converted to various user defined measuring units.
A unique feature of this product is that it employs a proprietary digital filtering system and recognition circuit. This feature allows the instrument to measure fluid velocities of clean liquids if the transducers are mounted downstream from a 90° elbow. The non-symmetrical hydraulic turbulence which occurs downstream of an elbow is captured, linearized and can be displayed as liquid velocity and volume. This capability is not available in conventional Doppler technology.
The D901/M flow meter can be successfully applied on a wide range of metering applications. The simple to program transmitter allows the standard product to be used on pipe sizes ranging from 1 - 120 inch [ 25 - 3050 mm ] pipe I.D. (With the small pipe transducer option, the pipe size range is 0.25 - 1 inch [ 6 - 25 mm]). A variety of liquid applications can be accommodated: raw sewage, reclaimed water, river water, plant effluent, mining slurries, sludge, etc. Because the transducers are non-contacting and have no moving parts, the flow meter is not affected by system pressure, fouling or wear. Standard transducers are rated to 250°F [121°C]. Optional high temperature transducers are rated to operate to 400°F [204°C].
PART 1 - INTRODUCTION
User Safety
Battery Backup
Product Identification
The D901/M employs modular construction and provides electrical safety for the operator. The display face contains voltages no greater than 9 Vdc and the metal work is electrically connected to Earth Ground. The display face swings open to allow access to user connections.
A rechargeable nickel-cadmium battery on the back of the display board retains all user-entered configuration values in memory for several years (at 25°C), even if power is lost or turned off. The ten year battery is continually trickle charged whenever line power is applied. A completely discharged battery recharges fully after 48 hours of instrument operation.
The serial number and complete model number of your D901/M is located on the inside of the transmitter’s front cover. Should technical assistance be required, please provide the Dynasoncs’ Customer Service Department with this information.

PART 2 - TRANSDUCER INSTALLATION
Transducer Mounting Considerations
Step A - Mounting Locations
CASE 1:
The transducers that are utilized by the D901/M contain piezo electric crystals for transmitting and receiving ultrasonic sound energy through the pipe wall.
The transducers can be mounted in three different configurations. The selection of the proper configuration is dependent on the liquid to be measured characteristics.
The three liquid characteristics, which will affect mounting location and orientation, are as follows:
CASE 1: Liquid that contains 25 to 10,000 PPM [1%] of 30 micron or larger suspended solids or aeration.
CASE 2: Liquid that contains greater than 10,000 PPM [1%] of 30 micron or larger suspended solids or aeration.
CASE 3: Liquid that contains fewer than 25 PPM of 30 micron or larger suspended solids or aeration and suspended solids and aeration content which is smaller than 30 microns.
Liquid that contains 25 to 10,000 PPM [1%] of 30 micron or larger suspended solids or aeration.
Select a transducer mounting location with adequate straight runs of pipe, both upstream and downstream, to achieve stable readings. Examples of minimum upstream and downstream requirements are included in Table 1.
Mount the transducers 180° apart and facing each other on the pipe. If the pipe is horizontal, the preferred mounting orientation is 3 and 9 o’clock, with 12 o’clock being the top of the pipe. Orientation on vertical pipes does not matter. See Figure 4.

may be influenced to various degrees.
Top View of Pipe
Figure 4
PART 2 - TRANSDUCER INSTALLATION
The mounting location and straight pipe requirements for CASE 2 liquid characteristics are the same as those describe in CASE 1. The difference will be in the location of the transducers on the pipe. As the discontinuities (suspended solids or aeration) reach a level of approximately 1% or 10,000 PPM, sound can no longer be reliably transmitted through the liquid as it has a tendency to scatter and absorb into the high concentration of
CASE 3:
Figure 5
discontinuity. To compensate for this, the D901/M transducers can be located on the same region of the pipe. In a horizontal pipe, mount the transducers at 2 o’clock and 4 o’clock positions. (Assuming 12 o’clock as the top of the pipe.) See Figure 5.
Liquid that contains fewer than 25 PPM of 30 micron or larger suspended solids or aeration. Or, liquid that contains solids or aeration which is smaller than 30 microns.
The transducers will be mounted 1 to 3 pipe diameters downstream from a 90° elbow. The orientation of the transducers on the pipe will be 180° apart and facing each other and 90° out of the plane of the elbow. See Figure 6.
PART 2 - TRANSDUCER INSTALLATION
STEP B - PIPE SURFACE PREPARATION
STEP C - TRANSDUCER MOUNTING
Figure 6
Before the transducer heads are bonded to the pipe surface, an area slightly larger than the flat surface of the transducer must be cleaned to bare metal on the pipe. (Plastic pipes do not require preparation beyond removal of paint.) Remove all scale, rust and paint. Thoroughly dry and degrease the mounting surfaces.
NOTE: Small pits in the piping surface typically do not significantly impact ultrasonic transmission or signal reception.
After selecting the applicable mounting location and preparing the piping surface as detailed in A and B, the transducer can be mounted to the pipe.
To assure an acoustically conductive path between the transducer face and the prepared piping surface, a coupling compound is employed. Enclosed with the D901/ M system is tube of Dow Corning RTV-732. This couplant is satisfactory for permanently mounting the transducers to the pipe. If the installation is temporary (less than a few days), Dynasonics recommends utilizing a silicone-based grease such as Dow Corning 111. The grease chosen must be rated to not flow at the temperature of the pipe.
PART 2 - TRANSDUCER INSTALLATION
PROCEDURE:
1. Select the proper number of transducer straps to allow a complete strap to go around the circumference of the pipe. See Table 2 - The straps can be connected together to make a continuous length.
Table 2 Pipe Sizes Straps Required
1” to 9” 10” to 19” 20” to 29” 30” to 39”
2. Wrap the strap around the pipe in the area where the transducers are to be mounted. Leave the strap loose enough to allow the transducers to be placed underneath. If multiple straps are being used, it can be beneficial to wrap electrical tape around all but one strap connection to secure the strap worm screws in place.
3. Spread an even layer of coupling compound, approximately 1/8 inch [3mm] thick, to the prepared transducer mounting areas of the pipe. Utilize Dow 732 for permanent mounting or Dow 111 for temporary mounting,
25 to 225 mm 1 250 to 480 mm 2 500 to 740 mm 3 760 to 1000 mm 4
4. Spread an even layer of coupling compound, approximately 1/8 inch [ 3mm ] thick, to the flat face of the two transducers.
5. Place each transducer under the strap with the flat face positioned towards the pipe. The notch on the back of the transducer will provide a mounting surface for the strap. The transducer cables must be facing in
PART 2 - TRANSDUCER INSTALLATION
the same direction for proper operation. See Figure 7. NOTE: Large pipes may require two people for this procedure.
6. Tighten the strap tight enough to hold the transducers in place, but not so tight that all of the couplant squeezes out of the gap between the transducer face and pipe. Ensure that the transducers are squarely aligned on the pipe.
Figure 7
7. Route the transducer cable back to the transmitter mounting area avoiding high voltage cable trays and conduits. Do not attempt to add additional cable to the factory supplied transducer cable. The D901/M processes very small signals, so the cable shield must be continuous. Excess cable may be coiled to take up extra length.
8. If the transducers are to be permanently mounted using Dow 732, the RTV must be completely cured before proceeding to Instrument Start up. Ensure that no relative motion between the transducer and pipe occurs during the 24 hour curing process. If Dow 111 grease was used for temporary operation of the D901/ M system, proceed with the Instrument Start-up procedures.
Transducer Installation is complete
PART 2 - TRANSMITTER INSTALLATION
Transmitter Installation
The enclosure should be mounted in an area that is convenient for servicing, calibration or for observation of the LCD readout.
1. Locate the transmitter within the length of transducer cable that was supplied with the D901/M system. If this is not possible, do not attempt to add additional cable to the transducer. Contact the Dynasonics factory to coordinate an exchange for the proper cable length. Transducer cables that are up to 300 feet [90 meters] are available.
2. Mount the D901/M transmitter in a location that is:
Figure 8
PART 2 - TRANSMITTER INSTALLATION
ELECTRICAL CONNECTIONS
♦ Where little vibration exist. ♦ Protected from falling corrosive fluids. ♦ Within ambient temperature limits - 22 to 160°F [30 to
70°C]
♦ Out of direct sunlight. A sun and weather shield is
available from Dynasonics. P.N. D003-899-001. Direct sunlight may increase temperatures within the transmitter to above maximum limit.
3. Mounting: Refer to Figure 8 for enclosure and mounting dimension details. Ensure that enough room is available to allow for door swing, maintenance and conduit entrances. Secure the enclosure to a flat surface with four appropriate fasteners.
4. Conduit holes. Conduit hubs should be used where cables enter the enclosure. Holes not used for cable entry should be sealed with plugs.
NOTE: Use NEMA 4 [ IP65 ] rated fittings plugs to maintain the water tight integrity of the enclosure. Generally, the left conduit hole (viewed from front) is used for line power; the right conduit hole for transducer connections.
5. If additional holes are required, (analog outputs, etc.) drill the appropriate size hole in the enclosure’s bottom. Use extreme care not to run the drill bit into the wiring or circuits cards.
To access terminal strips for electronic connectors, loosen the two screws in the enclosure door and open the door. Loosen the two thumb-screws on the inner display door and open the door.
1. Guide the transducer terminations through the transmitter conduit hole located on the right side of the

enclosure. Secure the transducer cable with the supplied conduit nut.
2. The terminals on the transducer cable are coded with wire markings. Connect the appropriate wires to the corresponding screw terminals in the transmitter. See
Figure 9.
NOTE: The transducer cable carries low level signals.
Do not attempt to add additional cable to the factory supplied transducer cable. If additional cable is required, contact the Dynasonics factory to arrange for an exchange transducer with the appropriate length of cable. Cables to 300 feet [ 90 meters ] are available.
The 4-20mA output is proportional to the flow rate measuring scale and can drive a load of up to 600 ohms. The output is isolated from earth ground and circuit low. Connect the load to the 4-20 mA screw terminals on the transmitter terminal block, matching polarity as indicated.
NOTE: An additional hole in the transmitter enclosure is required for outputs. Drill the hole in the the enclosure bottom taking care not to drive the drill bit into wiring or the circuit boards with the transmitter.
The pulse output is proportional to the flow rate measuring scale. This output may be used one of two ways:
♦ To drive a 12V logic device. ♦ To drive a low impedance, 12V device. Minimum
resistance 50 ohms.
The pulse output is adjustable from a range of 0 - 600 Hz to 0 - 10kHz via control R29 [CTR] located on the left side of the signal processing PCB in the back of the enclosure. The pulse width is fixed at 50 µ seconds. CTR “ - ” represents circuit low. CTR “ + “ represents 12 Vdc pulse output.
PART 2 - ELECTRICAL INSTALLATION
Optional 0 - 1 mA Output
Line Power
Figure 10
If the 0-1mA output has been installed on the D901/M, the connections are available on the screw terminal block in the transmitter. Connect a load of not more than 4 K ohms to the terminals. Adjust control R20 [1 mA] to fine tune the output to match the load impedance.
Connect line power to the screw terminals marked AC, AC and GND in the transmitter. See Figure 10. Utilize the conduit hole on the left side of the enclosure for this purpose. Use wiring practices that conform to local codes (National Electric Code Hand book in the USA). Use only the standard three wire connection. The ground terminal grounds the instrument, which is mandatory for safe operation.
CAUTION: Any other wiring method may be unsafe or cause improper operation of the instrument.
It is recommended not to run line power with other signal wires within the same wiring tray or conduit.
NOTE: This instrument requires clean electrical line power. Do not operate this unit on circuits with noisy components (i.e. Fluorescent lights, relays, compressors, variable frequency drives, etc.).
If this option is installed, the D901/M can be operated from a 12 Vdc source, as long as it is capable of supplying 1 Ampere. Observe proper polarity.
Optional 12 Vdc power
PART 3 - STARTUP AND CONFIGURATION
Before Starting the Instrument
Instrument Startup
Sensitivity Adjustment Control
Note: The D901/M flow meter system requires a full pipe
of liquid before a successful startup can be completed. Do not attempt to make adjustments or change configurations until a full pipe is verified.
Note: If Dow 732 RTV was utilized to couple the transducers to the pipe, the adhesive must fully cure before power is applied to the instrument. Dow 732 requires 24 hours to cure satisfactorily. If Dow 111 silicone grease was utilized as a couplant, the curing time is not required.
Procedure:
1. Verify that all wiring is properly connected and routed.
2. Set the SENSITIVITY Control to -2. This control is located on the inner door.
3. Apply power. The POWER indicator will illuminate.
4. Adjust the SENSITIVITY control so that the right-most LED on the SIGNAL STRENGTH bar meter just illuminates.
Note: It is undesirable to adjust the SENSITIVITY control to a position higher than necessary, as ambient noise can also be amplified. This noise can cause false readings to occur.
5. If the pipe is full of a flowing liquid, the READ indicator will illuminate and the display will begin reading fluid velocity as FPS (Feet per Second) or MPS (Meters per Second). It is normal to have low SIGNAL STRENGTH and FAULT indication at ZERO flow.
6. If a SIGNAL STRENGTH reading in the green portion of the bar meter could not be obtained, refer to the troubleshooting section of this manual.

PART 3 - STARTUP AND CONFIGURATION
Keypad Configurations
Modes of Operation
(covered in the previous sections of this manual) the D901/M can be keypad configured to provide select engineering unit readings of flow and a scaled 4-20mA output. Configuration inputs are made via the keypad and are stored by the microprocessor. The entries are retained by the flow meter’s backup battery in the event of power failure. If fluid velocity readings, FPS or MPS, are the only required measurement keypad configuration is not required.
The RUN/ENT key toggles the flow meter between the two modes of operation.
RUN Mode: This is the primary operating mode of the flow meter. The meter is in RUN mode when the readout is displaying flow as velocity (FPS, MPS) OR volume (GPM, LPM, LPS). In RUN mode the outputs are active and transmitting signals proportional to flow rate.
ENTRY Mode: This mode is used to view or change the configuration of the flow meter. When the D901/M ships from the Dynasonics factory, it contains the following Default configuration:

Attempting to enter values other than 1, 2 or 3 will result in an UNDER! or OVER! to be displayed. Non-whole number values will result in a RANGE! display. A legitimate value must be entered.
A few factors can influence the readings of the D901/M flow meter. The CAL entry allows the user to compensate for flow discrepancies without affecting the factory calibration. Examples of situations that can cause reading discrepancies are:
• Operation on liquids with sonic velocity carrying properties that are different than water.

If the RESET key is pressed again, all configuration constants will return to default values.
If the VOL. PULSE key is pressed, the accumulated flow will be erased and the display will return to zero.
In RUN Mode, pressing the decimal point once will suspend totalizer accumulation. Pressing the decimal point again will clear the total. Pressing it a third time will restart the accumulation from zero.
PART 4 - TROUBLE SHOOTING
CONDITION
Unit does not turn “ON” when power is applied
OVERRANGE light is ON
FAULT light is ON; low SIGNAL STRENGTH indication
POSSIBLE CAUSE
• Check AC connections.
• Test the fuse
• Ensure the terminal block located in the
upper left corner of the main PCB is secure
• Verify that ribbon cables between PCBs are connected.
• Increase the value of the FULL SCALE constant.
• Verify that fluid velocity is not greater than 20 FPS [6.08 MPS]
• Ensure that the transducers are properly mounted to the pipe.
• Verify that transducer connections are correct
• Ensure that the pipe is full of moving liquid.
• Increase SENSITIVITY so that right­most SIGNAL STRENGTH light just comes ON.
• On cleaner liquids, move the transducers closer to a 90
• On dirtier liquids, mount the transducers as described in CASE 3 of Part 2 of this manual.
• If the pipe has a polyethylene liner, move the transducers to another area. The liner may contain an air void at this location.
(continued)
o
pipe elbow.
PART 4 - TROUBLE SHOOTING
FAULT light is ON; low SIGNAL STRENGTH indication (continued)
Stability of flow readings are unsatisfactory
Erroneous Reading
• If GND connection and pipe are at different potentials, ground D901/M to pipe potential.
• If Variable Frequency Drives are being utilized, verify that the D901/M obtains a READ light when the pump turn OFF. If it does, contact the Dynasonics factory.
• Increase the DAMP constant from keypad.
• Increase the system time constant by
turning R17 (DAMP) clockwise till readings are satisfactory.
• Move transducers to a location further from piping tees, elbows, valves, filters, etc.
• Transducers mounted incorrectly.
• Another local ultrasonic instrument is
operating at about the same frequency [ consult the Dynasonics factory].
• Presence of large amounts of suspended solids or aeration. Use CAL constant to compensate.
• Sources of radiated interference are present. Apply appropriate shielding.
• An electrically noisy power supply is powering the D901/M. Power the meter with a circuit that does not power motors, ballasts or switching supplies.
Readings of flow at zero fluid velocity
• Verify that residual leakage and flow is not present. [I.e. leaking check valves]
• Verify that SENSITIVITY is not adjusted too high. With nominal flow running through the pipe, adjust SENSITIVITY control till the right-most bar meter light just comes ON.
